as noted by others, a little hard to find the first time. This doesn't have a gym; it's a room with three outdated exercise bikes.
The place is clean and quiet and a good location. it's just not well stocked with necessities: no soap, shampoo, dish soap or laundry detergent. there's only a microwave, no range. the microwave takes up the table space, but I guess you could move it if you want.
the TV isn't connected to cable or wifi, so why advertise it? must use an HDMI cable.
bed was a little firm, but not as bad as the average in Bangkok.
The bathtub and shower were nice and roomy, but the water splashes everywhere. This is not a big deal, but quite annoying. It could use some kind of curtain. One note: the bathtub step up is quite high, so if you have mobility issues, be careful. It is also slippery because there isn't a shower curtain.
overall, it's ok but only if you pay less than twenty bucks. keep looking.
